Description. FEMALE. Length 1.9 mm.

Scape pale brown, pedicel and flagellum dark brown. Frons and vertex black with metallic bluish-green tinges. Mesoscutum and scutellum black with metallic blue and purple tinges. Coxae dark and metallic; femora dark brown; fore tibia pale brown, mid and hind tibiae dark brown; fore tarsus with tarsomere 1 yellowish-brown and 2–4 dark brown, mid and hind tarsi with tarsomeres 1–3 yellowish-brown and 4 dark brown. Wings hyaline. Gastral tergites dark brown and shiny.

Flagellum with 3 small and discoid anelli, 2 funiculars and a 3-segmented clava (Figs 74, 92). Frons and vertex with strong, raised reticulation; frons with scattered setae. Antennal scrobes and frontal suture absent. Occipital margin rounded. Eyes with scattered short hairs.

Mesoscutum and scutellum convex. Mesoscutum 0.7X as long as wide; with strong, raised reticulation; midlobe with 3–4 pairs of setae; notauli indistinct. Scutellum 1.4X as long as wide; with strong, raised reticulation; with 1 pair of setae; with a narrow slit between scutellum and axillae. Propodeum with posterolateral part drawn out into a blunt point; propodeal callus with 6–7 setae and with 3–4 additional setae inside spiracular sulcus; without a median carina; entire propodeal surface reticulate. Forewing with 2 setae on dorsal surface of submarginal vein; costal cell bare; ventral surface just below marginal vein with a setose area; speculum very large and open below.

Petiole not visible, but presumably small. Gaster circular; gastral tergites smooth and partly shrivelled.

Ratios. HE/MS/WM = 37.0/1.0/16.0; POL/OOL/POO = 38.0/16.7/1.0; WH/WT = 1.2; LW/LM/HW = 1.9/1.0/1.5; PM/ST = 1.0; MM/LG = 1.7.

MALE. Length 1.6 mm.

Colour as in female.

Flagellum with 3 small discoid anelli, remaining 5 flagellomeres distinctly separated (Figs 75, 93). Eyes smaller than in female, the posterior ocelli situated away from occipital margin. Head otherwise similar to female

Mesosoma as in female.

Ratios. HE/MS/WM = 3.1/1.0/1.9; POL/OOL/POO = 10.5/4.4/1.0; MM/LG = 1.3.

Distribution. Brazil.

Biology. From galls on Copaifera langsdorffii (Fabaceae) .

Material examined. Holotype female “ BRAZIL, Sao Paulo, Jaguariuna, galls on Copaifera langsdorffii, collected 18.ix.1997, emerged i.1998, M. Tavares, V. Costa, C. Azevedo, N. Perioto, J. LaSalle”, in MZSP. Paratypes: 2 females 1 male with same data as holotype (1 female BMNH, 1 female 1 male MZSP).

Etymology. Named for the famed Brazilian entomologist, Angelo Moreira da Costa Lima. This name was chosen because it is the manuscript name used for this species by Guimarães (1957).

Remarks. We have also examined 15 specimens belonging to this species treated by Guimarães and collected in Paraopeba, Minas Gerais (in DCBU). The material is in poor condition, with specimens badly broken, and as such they are only included in this paper for their historic interest — but they are not included in the description and are hence not type material.
